为css滑块添加计时功能

Question

我一直试图了解这个问题好几天，但需要你的帮助css guru！

我有一个纯css滑块，它使用了一些很棒的控件。问题是我希望滑块也像定时功能一样自动移动。我试图用关键帧做到这一点，但没有运气。

这怎么可能？

HTML：

    <input type="radio" name="slider" class="slide-radio1" checked id="slider_1">
    <input type="radio" name="slider" class="slide-radio2" id="slider_2">
    <input type="radio" name="slider" class="slide-radio3" id="slider_3">
    <input type="radio" name="slider" class="slide-radio4" id="slider_4">

    <div class="sliderPagination">
        <label for="slider_1" class="page1"></label>
        <label for="slider_2" class="page2"></label>
        <label for="slider_3" class="page3"></label>
        <label for="slider_4" class="page4"></label>
    </div>

    <div class="next control">
        <label for="slider_1" class="numb1"><i class="fa fa-arrow-circle-right"></i></label>
        <label for="slider_2" class="numb2"><i class="fa fa-arrow-circle-right"></i></label>
        <label for="slider_3" class="numb3"><i class="fa fa-arrow-circle-right"></i></label>
        <label for="slider_4" class="numb4"><i class="fa fa-arrow-circle-right"></i></label>
    </div>
    <div class="previous control">
        <label for="slider_1" class="numb1"><i class="fa fa-arrow-circle-left"></i></label>
        <label for="slider_2" class="numb2"><i class="fa fa-arrow-circle-left"></i></label>
        <label for="slider_3" class="numb3"><i class="fa fa-arrow-circle-left"></i></label>
        <label for="slider_4" class="numb4"><i class="fa fa-arrow-circle-left"></i></label>
    </div>


    <div class="slider slide1">

    </div>
    <div class="slider slide2">

    </div>
    <div class="slider slide3">

    </div>
    <div class="slider slide4">

    </div>
</div>
